MEANS FOR MOUNTING WHEELS ON THEIR SHAFTS.

SPECIFICATION forming part of Letters Patent No. 282,322, dated July 31,1883.

Application filed June 15, 1893. (No model.)

wheel attached to the shaft, which is shownin section. Fig. 2 is asection 011 line mm, Fig. 1; and Fig. 3 is a longitudinal centralsectional View of a wringer-roll embodying my invention.

A represents the shaft of a wringer-roll, which is shown inthes1ight1y-flattened state as they usually come from the rolls, and is aused in thisunfinished condition, cut to the proper length, and thevulcanized rubber D, which-forms the surface to act on the clothes,attached in the usual manner.

I have discovered that by making the gears 13 of malleable iron andcasting thereon the disk 0, along with the cogs d, and coring thecenter, and then shaping it by means of a punch, the gear B can beplaced on the shaft cold, by either screw or hydraulic pressure, andwill draw to fit the shape of the rolled shaft without splitting orbursting the gears, and without the necessity of employing feathers,pins, or set-screws while providing a cheaper and better mode ofsecuring the gearwheels to the shaft for light worksuch as is requiredin clothes-wringers-for which my invention is chiefly intended. If thedisk 0 be omitted, or the gears made of cast-iron, or the shaft turnedor finished, the gears cannot be properly pressed on the shaft.

After the rolls and gears are attached to the shaft it is turned orfinished, if desired, to form proper journals.

I claim The process of making wringer-rolls by taking unfinished rolledshaft-iron and malleable gears B, having a disk, 0, and gears cast thereon and then pressed cold on the unfinished shaft by suitablepower-pressure, substantially as herein set forth.

In testimony whereof Ihave hereunto set my hand.

'HENRY C. HOPKINS.
